Description

Technical Field

[0001] The utility model relates to the technical field of globe valves, and particularly relates to an integrated combined globe valve. Background Technique

[0002] The globe valve is one of the most widely used valves. It is widely popular because of the small friction between the sealing surfaces during the opening and closing process, relatively durable, small opening height, easy to manufacture, and convenient to repair. It is applicable not only to medium and low pressures but also to high pressures. The closing principle of the globe valve is that relying on the valve stem pressure, the sealing surface of the valve flap is closely attached to the sealing surface of the valve seat to prevent the medium from flowing through. During the use process, the globe valve is often used to control the gas-liquid flow. When controlling multiple media, multiple globe valves are often used for control, which results in more connected pipelines, large space occupation, and due to the intricate arrangement of the pipelines, it is difficult to carry out maintenance when a failure occurs, making the maintenance inconvenient. Therefore, we propose an integrated combined globe valve. Content of the Utility Model

[0003] The utility model provides an integrated combined globe valve, which solves the problems raised in the above background technique.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: an integrated combined globe valve, including a globe valve main body, a first connection port is opened on the globe valve main body, and a second connection port is opened on the globe valve main body. The first connection port is communicated with the second connection port. The first connection port is one, and the second connection ports are multiple and the second connection ports are located outside the globe valve main body. A channel for the medium to flow is formed between the first connection port and each second connection port. A control valve flap is movably connected in each channel. The control valve flap can close the channel. At the same time, a driving valve stem for separately opening the control valve flap is assembled in the middle inside the globe valve main body, and a rotating wheel for controlling the driving valve stem is assembled outside the globe valve main body.

[0005] Optionally, the bottom end of the driving valve stem passes through the globe valve main body and extends into the first connection port to close the first connection port. The driving valve stem is located inside the globe valve main body and is movably connected to the globe valve main body.

[0006] Optionally, a threaded valve stem is movably sleeved at the top end of the driving valve stem. The threaded valve stem is threadedly sleeved with the globe valve main body, and the top end of the threaded valve stem extends out of the globe valve main body and is movably connected to the rotating wheel.

[0007] Optionally, the rotating wheel is movably sleeved on the top of the globe valve main body, and a limiting spring is fixed at the top end of the threaded valve stem. The top end of the limiting spring is fixed to the inner wall of the rotating wheel.

[0008] Optionally, one end of the control valve flap passes through the globe valve body and abuts against the driving valve stem, and a plurality of valve opening notches are formed at the same height on the outer side of the driving valve stem.

[0009] Optionally, the valve opening notches correspond to the control valve flaps one by one, and the plurality of control valve flaps are not at the same height and are evenly distributed in the globe valve body.

[0010] Optionally, outlet valve springs are fixed on both sides of the control valve flap, and one end of each outlet valve spring is fixed to the globe valve body.

[0011] The utility model has the following beneficial effects:

[0012] 1. For the integrated combined globe valve, by rotating the runner, the threaded valve rod is driven to move, and then the driving valve stem can move, and further the valve opening notch can move. When the valve opening notch moves to the corresponding control valve flap, its channel is opened to achieve the single-pass effect, and further the connection of multiple pipelines can be realized, making its use more convenient.

[0013] 2. For the integrated combined globe valve, when rotating, the threaded valve rod can move into the runner, and then the runner can always wrap the threaded valve rod, avoiding the threaded valve rod from contacting the outside world and accelerating the oxidation of the threaded valve rod, ensuring the tightness of the connection of the threaded valve rod. And under the action of the limiting spring force, a side pressure can be given to the threaded valve rod to increase the friction between the threaded valve rod and the globe valve body, making the fixation of the threaded valve rod more stable.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 5 , an integrated combined globe valve, including a globe valve body 1, on which a first connection port 2 is opened, and a second connection port 3 is opened on the globe valve body 1. The first connection port 2 is communicated with the second connection port 3, so that the medium can flow smoothly. There is one first connection port 2, and there are multiple second connection ports 3 and the second connection ports 3 are located outside the globe valve body 1, so that the effect of controlling multiple media can be achieved. A channel for the medium to flow is formed between the first connection port 2 and each second connection port 3. A control valve flap 8 is movably connected in each channel. The control valve flap 8 can close the channel. Under the limitation of the globe valve body 1, the control valve flap 8 can move along a fixed track, so as to control the opening and closing of the channel. And a driving valve stem 7 for controlling the individual opening of the control valve flap 8 is assembled in the middle of the globe valve body 1. By moving the driving valve stem 7, the individual opening of the control valve flap 8 can be completed, so that the medium can flow individually. At the same time, a runner 4 for controlling the driving valve stem 7 is assembled outside the globe valve body 1. By screwing the runner 4, the movement of the driving valve stem 7 can be controlled, making its control more convenient. When the device is connected reversely so that the first connection port 2 feeds in, the effect of diverting the medium can be achieved, and the diverted branches can be controlled individually.

[0022] Please refer to Figures 1 to 5 , the bottom end of the driving valve stem 7 passes through the globe valve body 1 and extends into the first connection port 2 to close the first connection port 2. The driving valve stem 7 is located inside the globe valve body 1 and is movably connected to the globe valve body 1. Under the limitation of the globe valve body 1, the driving valve stem 7 can move along a fixed track.

[0023] Please refer to Figures 1 to 5, a threaded valve rod 6 is movably sleeved on the top end of the driving valve rod 7. Under the limitation of the driving valve rod 7, the threaded valve rod 6 can rotate at a fixed position on the driving valve rod 7, thus ensuring that the rotation of the threaded valve rod 6 will not affect the driving valve rod 7, and ensuring its smooth operation. The threaded valve rod 6 is threadedly sleeved with the main body 1 of the globe valve. When the threaded valve rod 6 is rotated, the threaded valve rod 6 can move, and due to the frictional force between the threaded valve rod 6 and the main body 1 of the globe valve, the threaded valve rod 6 can be relatively fixed. And the top end of the threaded valve rod 6 extends out of the main body 1 of the globe valve and is movably connected with the runner 4. Under the limitation of the runner 4, the threaded valve rod 6 can move along a fixed track, and under the action of the runner 4, the threaded valve rod 6 can be protected, and the service life of the threaded valve rod 6 can be extended.

[0024] Please refer to Figures 1 to 5 , the runner 4 is movably sleeved on the top of the main body 1 of the globe valve. Under the limitation of the main body 1 of the globe valve, the runner 4 can rotate at a fixed position on the main body 1 of the globe valve. And a limiting spring 5 is fixed at the top end of the threaded valve rod 6, and the top end of the limiting spring 5 is fixed to the inner wall of the runner 4. Thus, the limiting spring 5 can give a lateral pressure to the threaded valve rod 6, increasing the frictional force between the threaded valve rod 6 and the main body 1 of the globe valve, making the fixation of the threaded valve rod 6 more stable.

[0025] Please refer to Figures 1 to 5 , one end of the control valve flap 8 passes through the main body 1 of the globe valve and abuts against the driving valve rod 7, thus enabling the control valve flap 8 to close the passage. And a plurality of valve opening notches 9 are opened at the same height on the outer side of the driving valve rod 7. Thus, the movement of the valve opening notches 9 will not open all the control valve flaps 8 at the same time, thereby realizing the effect of individual control of the control valve flaps 8.

[0026] Please refer to Figures 1 to 5 , the valve opening notches 9 correspond to the control valve flaps 8 one by one, and the plurality of control valve flaps 8 are not at the same height, and they are evenly distributed in the main body 1 of the globe valve. Thus, the valve opening notches 9 will only control the opening of one control valve flap 8 at a time, thereby realizing the effect of individual control of the control valve flaps 8.

[0027] Please refer to Figures 1 to 5 , outlet valve springs 10 are fixed on both sides of the control valve flap 8, and one end of each outlet valve spring 10 is fixed to the main body 1 of the globe valve. Under the action of the elastic force of the outlet valve springs 10, the control valve flap 8 can smoothly move into the valve opening notches 9, thereby opening the passage.

[0028] In summary, for the integrated combined stop valve, during use, when the rotating wheel 4 is screwed, driven by the rotating wheel 4, the threaded valve rod 6 rotates, and then the threaded valve rod 6 can move. The threaded valve rod 6 drives the driving valve rod 7 to move. The driving valve rod 7 first opens the first connection port 2, and then the valve opening groove 9 can move to the corresponding control valve flap 8. Under the action of the elastic force of the outlet valve spring 10, one end of the control valve flap 8 can move into the valve opening groove 9, and then the control valve flap 8 is opened, enabling the control valve flap 8 to be opened separately, so that the first connection port 2 can communicate with it. At the same time, when the threaded valve rod 6 rotates, the threaded valve rod 6 can move upward and then move into the interior of the rotating wheel 4. The limiting spring 5 is compressed. Under the action of the elastic force of the limiting spring 5, a lateral pressure can be applied to the threaded valve rod 6, increasing the friction between the threaded valve rod 6 and the stop valve body 1, making the fixation of the threaded valve rod 6 more stable.
